# Projection receipts Copy `example-projection-receipt.json` at window start and fill in the live engagement id, `projected_at`, `expires_at`, and identity *names* from the custody procedure. Never put token values, passwords, or registry payloads here. Live admission: ```sh PYTHONPATH=src python3 -m whitehat_security.cli admit-plane \ engagements/.json targets/audit-core-e2.json \ --receipt engagements/receipts/.json ``` Without `--receipt`, live admission fails closed and requests no credential.
